6 Claims.

The invention relates to a tubular skate, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

5. The invention consists essentially in the novel form of the skate sections and their assembly, as pointed out in the claims for novelty following a description in detail of the parts and the operations contributory to finishing the skates.

The objects of the invention are to reduce to a very considerable extent the number of operations required to build the skate and eliminate the necessity of soldering; to produce a finished article of lighter weight and less susceptible to damage because of the integrality of the elements comprising the structure; to lower the first costs in production by the saving of material and the minimizing of the expenditures for labor as well as materially increasing the output in a given 20 time; to eliminate any weaknesses incident to conventional methods in joining tubular parts and strengthening the construction generally by properly seaming these parts; and generally to provide a skate that will stand up well under the 25 most diificult conditions in use and prove satis factory to the player or skater as well as being a skate of the best quality procurable at a reasonable price.

In the drawings, Figure 1 is an elevational view 30 of the skate.

Figure 2 is an elevational view of a skate section.

Figure 3 is a plan view of the top of the skate showing tubular pieces out before seaming.

Figure 4 is a plan view showing the blade partly fused extending from the complete tube.

Figure 5 is a plan view showing an upturned piece from a skate section instead of an insert piece.

Figure 6 is a cross sectional view on the line 66 in Figure 3, with the cups unseamed.

Figure 7 is a cross sectional view on the line 7-7 in Figure 1, showing the tube parts and cups with lock seamed and finished.

Figure 8 is an enlarged cross sectional view of the tubes on the line 88 in Figure 1.

Figure 9 is an enlarged cross sectional view of the tube parts showing the rolled seam modified.

Figure 10 is a cross sectional view of tube parts,

50 showing the insert piece in the blades in modified --form.

Figure 11 is a fragmentary detail showing the bracket from the front plate welded to the blade.

Figure 12 is a cross sectional view showing the 1 blade flanges before fusing for a racing skate.

Figure 18 is a cross sectional View showing the reinforcing rib resulting from the rolled seam at the closed upper end of the tube halves taken approximately midway of the distance between cups on the line 13l3 in Figure 1.

Like numerals of reference indicate corre sponding parts in the various figures.

Referring to the drawings, the front plate indicated by the numeral 15 and the back plate indicated by the numeral 16 are stamped out as customary in tubular skates, each of these plates having the cup openings 17 and 18 respectively, these cup openings being surrounded by the annular upstanding flanges 19 and 20 respectively.

The tube 21 and the cups 22 and 23 are made in halves and terminate in their torpedo shaped front ends 24 and in their torpedo shaped rear ends 25.

Each half of the skate frame constituting longitudinal halves of tube and cups is formed with the flange 26 the flange 26 on the one half being higher than the flange 26 on the other half, both of these flanges extending into the flanges 27 and 28 projecting upwardly and outwardly from the cups 22 and 23 respectively being inserted through the openings 17 and 18 respectively and cooperating with the flanges 19 and 20 respectively in making the joints in the form of roll seams.

The outer blade parts 29 and 30 extend as flanges from the lower sides of the tube halves and the filler strip 31 is inserted therebetween, and these three parts, the part 29, the part 30 and the insert 31 are fused together and form the blade 32. The extending front ends of the blade parts 29. 30 and 31 are divided and form the u brackets 33 and 34 which are secured to the front plate 15, the blade 32 itself being curved upward- 1y at the front end 35 following the torpedo shape 24, while the rear end of the blade is rounded oil at 36 as customary.

It will now be seen that the blade and the tube are integral, eliminating a very expensive part, namely the blade itself as customarily made and materially strengthening the whole structure of the skate.

The flanges 26, 27 and 28 are look seams, the flange on one half being turned over and rolled on the flange of the other half forming a roll seam, and at the same time a strengthening rib 37 on the tube and strengthening ribs 38 on the cups, which is equivalent to adding a reinforcing structural member to the tube and reinforcing structural members to the cups.

The upper ends of the cups are looked over the flanges 19 and 20 by the same roll seam method and this roll scam in each case, namely the roll seam 39 and the roll seam 40 are flattened down in the annular recesses 41 and 42 at the bases of the flanges 19 and 20 respectively in the plates 15 and 16 respectively.

In Figure 9 the row of seams 43 are turned inwardly making a perfectly flush tube on the outside. The same may be done with the cups if it is found advisable in very finely finished and ornamental skates.

In Figure 11 the blade parts terminate at the front edge and are not offset, in place the bracket 44 is secured to the front plate and extends downwardly, and is welded to the said blade parts becoming integral therewith.

In Figure 10 the insert 31 is omitted and in place, one of the blade parts is turned inwardly, that is to say, the flange 45 forming the blade part is practically of double depth, as compared with the flange 46, and this double depth flange part is turned inwardly as shown at 4'7. If it is desired to have a heavier part, both flanges may be turned inwardly to form the blade parts and on some occasions when the skates are used for different purposes, there may be one or more inserts in addition, or there may be several inserts or simply the single flanges for racing skates where a thin blade is desirable.

It will be understood from the description herein, that the structural features of this skate are largely for facility in manufacturing and for economy in regard to the use of material. Naturally in an article of this kind, the metal is of a superior quality, and therefore costly and under present methods the wastefulness is very great, take for example the blades, there is a lot of scrap in cutting out these blades and no way of saving it.

Then the welded seams are not at all as satisfactory as rolled seams and the strengthening rib is entirely missing for it will be noticed that the welding of the tube flanges and cup flanges in conventional construction is not at all the same as welding two pieces of metal in one mass or rather fusing them in one mass. Of course all tubes are not made in the same way. There are even now different methods of construction, but none is known which furnishes a reinforcing rib and a tight joint at the same time, neither is it known to combine the tube and the blade in one structural feature.

What I claim is:- l. A tubular skate comprising a tube longitudinally divided into halves, a flange at the upper edge of one half fitted into a rolled flange at the upper edge of the other half whereby a reinforcing rib is formed and the lower edges of the halves being extended in parallel flanges spaced and closed by an insert adapted to be fused with said flanges and forming therewith a lower tube joint and the skate blade.

2. A tubular skate comprising a tube longitudinally divided into halves and interrupted by bulges forming cups and having a flange at the upper edge of one half fitted into a rolled flange at the upper edge of the other half whereby a reinforcing rib is formed and the lower edges of the halves being extended in parallel flanges spaced and closed by an insert adapted to be fused with said flanges and forming therewith a lower tube joint and the skate blade.

3. A tubular skate comprising a tube longitudinally divided into halves and forming cups and blades attached to the superstructure of the skate and having a flange at the upper edge of one half fitted into a rolled flange at the upper edge of the other half whereby a reinforcing rib is formed and the lower edges of the halves being extended in parallel flanges spaced and closed by an insert adapted to be fused with said flanges and forming therewith a lower tube joint and the skate blade.

4. A tubular skate comprising a tube longitudinally divided into halves and having a flange at the upper edge of one half fitted into a rolled flange at the upper edge of the other half whereby a reinforcing rib is formed and the lower edges of the halves being extended in parallel flanges spaced and closed by an insert adapted to be fused with said flanges and forming therewith a lower tube joint and the skate blade and a bracket from the superstructure fused to said blade.

5. A tubular skate comprising a tube longitudinally divided into halves and having a flange at the upper edge of one half fitted into a rolled flange at the upper edge of the other half whereby a reinforcing rib is formed and the lower edges of the halves being extended in parallel flanges, one flange being extended and upwardly turned to form an insert adapted to be fused with the downwardly turned portions and together therewith forming the skate blade.

6. A tubular skate comprising a superstructure and a supporting tube and integral cups in halves jointed at the edges whereby a reinforcing rib is formed and at the lower edges constituting a blade or runner.
